My invention relates to harvestinglnachines having the usual tractionwheel as a source of power that may be transmitted to other operativeparts of the machine, and consists in providing a motor attachmentsupported vupon the harvester frame and means for transmitting powertherefrom to a power shaft having-operative connection with the tractionwheel, there being a diferential gear connect-ionv between the twosources of power; the object of my invention being to provide anauxiliary source of power constantly available in a manner to take thewhole load, as circumstances may require. l attain this object by means'of the mechanism illus trated by the' accompanying drawings, in

ing mounted upon a fixed part of thc trame f and operative in common wayto disengage the clutch members.

2l represents a member ot a common form of differential gear mechanismsecured to the shaft 5 and provided with a pinion 22 rotatably mountedupon a radially arranged pin 23 connected with member 21 and meshingwith gear wheel l5.

24 represents a large sprocket wheel rctatably mounted upon shaft 5 andhaving integral therewith a bevel gear member 25 that meshes with pinion22 opposite the gear wheel 15.

26 represents a motor mounted upon thc platform 27, secured 'to thewheel trame, and including a crank shaft 28 having ily wheels 29 andasprocket wheel 3 0 secured thereto, and 31 represents a sprocket chainconnecting sprocket wheels and 2l.

In the operation ol the machine motion is transmitted from the tractionwheel to the clutch sleeve 12, and through it to gear wheel 15, and atthc same time the motor is transmitting its power in a manner to drivethe sprocket wheel 2l and gear wheel 25 in the same direction, the twogear wheels being connected with the differential gear member 21 bymeans of pinion 22, the combined power ot' the motor and traction wheelis communicated to the cross shaft in a dii ferential manner, the speedof the motor being governed in a manner to drive the operative parts ofthe machine at the proper speed when the dra l't team is advancing atanormal rate. lt that rale he exceeded the traction wheel exerts morethan its normal power to the engine, and il the rale he re duced theengine takes more of the load. Again, if the normal rate et advance ofthe team is exceeded, the speed ot the operative parts .of the harvesteris increased proportionately` and it' that rate is reduced it is alsotrue that the speed ot' the operative parts is reduced; thus, if theteam isstanding, 'the power of the motor acts to drive the operpowerfrom said equalizing gearing to the operative parts of lhe harvester,whereby said parts may be operated by either or both sources of. power,Substantially as and for the purpose described.

8. In combination with a harvesting machine including a traction Wheel.as the source of power, of an auxiliary motor, equalizing gearing havingone member rotal'ablyconnected with said motor and having another memberrotatably Vconnected with said traction Wheel7 and means for'transmittin ower from said erualizinv' 2:1

gearing to the operative parts of said harvester, whereby said parts maybe operated by both sources of power with speeds proportionate to therate of advance of the machine.
